Abstract
The invention discloses a high against pressure technology of vaulted sealing element, which comprises the following steps: A, producing a body with elastic material; B, producing the end face of the body as archy; C, providing a steel sheet in the body. This invention possesses reasonable craft, good idea and simple structure, which can be spreaded widely.
Description
Technical field
The present invention relates to technical field of valve manufacturing, specifically, relate to a kind of high pressure resistant technology of control piece of automatic on-off of drain valve.
Background technique
Present known fire hydrant automatic drain valve all is to utilize spring that counterpressure is provided basically.When hydraulic pressure was high in valve body, water pressure overcame spring force, spring force overcomes water pressure when hanging down, thus the automatic on-off drain valve, its complex structure.
Summary of the invention
The objective of the invention is to, provide a kind of and can effectively overcome above-mentioned defective, high resistance to compression and counterpressure can be provided is with the high pressure resistant technology of the arched sealing member of automatic on-off drain valve.
For achieving the above object, the present invention adopts following technological scheme: a kind of high pressure resistant technology of arched sealing member, and mainly comprising following steps: A. provides the end face of the body B. body that an elastic material makes to make arch; C. provide a steel disc in the body.
Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: technology of the present invention is reasonable, be skillfully constructed, the high pressure resistant arched sealing member that produces directly utilizes the elasticity of sealing member material and arch to make counterpressure, and high resistance to compression, make the best use of everything, simple in structure, overcome the baroque defective of conventional art effectively, have promotional value.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is the structural representation of the high pressure resistant arched sealing member that produces of the present invention.
Embodiment
A kind of high pressure resistant technology of arched sealing member mainly comprises the body that following steps: A. provides an elastic material to make; B. the end face of body is made arch; C. provide a steel disc in the body.The structure of the high pressure resistant arched sealing member that the present invention is produced below in conjunction with accompanying drawing describes in further detail.A kind of arched sealing member of high resistance to compression automatic drain valve is made up of the body 10 that elastic material is made, and the end face of body 10 is arch, and body 10 is embedded with a steel disc 20.Its working principle of brief description is worked as valve inleting water, and hydraulic pressure raises in the body, the outlet that drain cock joint is blocked in the arched sealing member distortion.When valve body is closed, hydraulic pressure descends in the body, and arched sealing member is replied, the drain cock joint draining.
